Nightmare Fuel / Mini Monsters

• Rattus Sapiens' plan to destroy Villa Susto: Distribute the lethal Porcelain Poison by the water network. Even if it's Played for Laughs, the fact that it would have all people in the town killed if he succeeded is truly horrible.
• Miss Hit's Ax-Crazy demeanor can be terrifying, especially in the final battle.
• In one of the stories of the third album, Frank's mother is seen giving a cake by opening her stomach. Also doubles as Squick.
• The end of the fourth album gives us the main characters eating Arrmando, the giant spider. Just... Ugh.
  • And before that, Arrmando el Arraña's creepy obsession to eat all monsters. Which makes his Eaten Alive end as (somewhat) Laser-Guided Karma.
